Esperite and Prase Physical Properties

Esperite and Prase Chemical Formula

While comparing Esperite and Prase physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Esperite and Prase chemical formula.

• Chemical formula of Esperite- PbCa 3Zn 4(SiO 4) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Prase- SiO 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Esperite and Prase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Esperite and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Prase Optical Properties during the identification of gemstone. Specific gravity of Esperite is 2.64-2.69 whereas that of Prase is 2.64-2.69.
